-..i l. l I l l IMPROVEMENT :N FILTERS..

Thelschleldulea'eferred to in these Letters Patent' and making part of the same.

ville, in thecounty of Boyle and in' the State 'of Kentucky, have invented certain new and useful Improvelnents in Anti-fi'eezing-llilters; andldo hereby.

declz'u'ethat the tbllowing is a full, clem-,and exact being `had tothe accompanying`- drawings and to the letters of reference marked thereon, which form apart of this specification; .i i i l i i' "The natureof my invention consists in the con- .struction and arrangement of an anti-freezing filter for cisterns, as `will beihereinafter-.fully setlforth.

In order to enable others, skilled in theart to` which myinvention appel-talus to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, which y representa longitudinalzvertical section ofiny filter.

Areprescnts the outside cylinder, within which is placed a bottom, B, andtwo sieves, C and D.

Between the bottorn B`aild the lower sieve C, is al1 open space, while `inthe space between the lower sieve i C and the upper` one D i'splaced some suitable kind .offiltering material, E. i

.A lidGr, is fitted tightly on top of the cylinder A. Through this lid passesthe receivingvpipe H, which leads downwardthi'ough `the two sievcs and the filterf ing material, opening orending in the space below `thelower sieve.`

The water entering [ills this space, and rises through the filteringr material E, and is discharged into the cistern, through a central discharge-pipe, I, leading from the center of the upper sieve D downward through the bottom B. v Through the filteringk material E, opening into the space above the bottomB, is an. air-tube, J, which ad- Vini/ts enough air to let the water run freely.v

i Through this air-tube runs a rod, K, to operate a valve, L, 4inthe bottom B, said valve leading into an elbow, M, vfor the purpose of turning olf the water, so.

as not to iiow into the cistern. This valve is so constructed that, when shut, it will allow sufficient water i to leak through, so as to prevent'it from freezing.

On the rod` K is a catch, a., which hooks onthe np- 'per sieve D, `to hold the valve L open.

Haviugthus fully described my invention,

.\Vhat I claim as new, and desire to secure by Letters latent, is-

The arrangement, within the cylinder A, of the bottoni B, sieves C D, filtering materiallil, `receiving-pipe H,"and discharge-pipe I, all substantially as shown and described.- i

In testimony that I cla-im the foregoingI as my own, I aiix my signature in presence of-'two witnesses.
